	# This project is CUDA-core: its runtime stack (cupy-cuda13x and the cudawarped
	# CUDA OpenCV build) has no CPU/macOS wheels and cannot even `import` without an
	# NVIDIA driver, so a GPU-less runner cannot install the project. CI therefore
	# does NOT install it, type-check, or run tests — those run locally on a CUDA
	# machine (`uv run ty check`, `uv run pytest`). CI keeps only the checks that
	# are cheap, deterministic, and need no GPU: ruff (static, isolated) and
	# lockfile freshness.

	# Run ruff in isolation (uvx): it reads [tool.ruff] from pyproject but

	# the dev group's ruff so CI and local agree on formatting/lint rules.
